IN 1989, Mike is a star on the school basketball court, a scout in the stand and a bright future in his grasp.

But he throws it all away to share his life with his pregnant girlfriend, Scarlet.

Almost 20 years later, Mike's glory days are behind him. His marriage has fallen apart, he has been passed over for promotion, his teenage children think he's a loser and he is staying with his high school friend, Ned.

Then, miraculously, he is transformed back to the age of 17 and has a chance to recapture his best years.

High School Musical's Zac Efron stars as the young Mike, with Friends' Matthew Perry as the adult version, in comedy 17 AGAIN (12A).
